[0 all whom it 'riiag concern:

Be it known that 'l, EDWARD E. SILK, of Chicago, in the county of Cookand State of Illinois, have invented a certain new, useful, and ImprovedFlexible Fluid-Joint, of which the following a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to unike and use the same.

My invention relates. to improvements in flexible joints for pipes, andparticularly for pipes ot'large diameter.

The object of my invention is to provide a flexible joint for fluidconveying pipes, especially for those of a larg diameter,'in which shallbe metallic and which shall be tight whether under high or low pressure.

A further and particular object of my invention is to provide a joint ofthe class packing equip the same with means for compressing the packingtherein without altering the adjustment of the metallic parts, andwithout permitting the packing to escape therefrom by passing about thecompressing member.

A. further object of my invention'is to provide a joint of the classmentioned with menus for taking up the Wear'incident to usage. I

With these objects in'view, my invention consists in a bull and socketjoint for fluid conveying pipes, comprising a ball member and n uvo-pnrtsocket member, a packing pocket in one part of said socket member,preferably extending inwardly to a plane beyond the center of the socketand a metallic joint or opening" between the parts of the socket member,and adapted 1') both retain the soft packing in the pocket and compressit therein. 1

My invention further consists in various details of construction, and incombinations of parts, all as described in detail hereinafter andparticularly pointed out in the appended claims.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification, and in whichFigurel is a sectional view of a fluid joint embodying my invention.Fig. 11 is an. en-

pocket, and. to

all engaging and holdin surfaces larged detail viewillustrating, onscale, the packing and packing pocket together with the metallicclosure.

Referring to the drawings, 1 indicates the ball member, and 2, 8, thetwo-part sockct member. The part. 2 of the socket member is providedwith an annular packing pocket 4, extendinginwardly to a plane beyondthe center of the socket. The bottom of the pocket 1 is defined by anannular flange or rib flhis rib C(JlltUZtS the bull member l,cii'ectnally closing the bottom of the pocket 4-. As the center of theball is above the plane of the flange 5, the [hinge contacts the bullupon a scroll. circle of the sphere.- Consequently, the ball is movedinwardly to take up the wear, it presents constantly increasing circlesto the rib 5. This takes up all wear at that point, and maintains atightly closed joint at the'bottom of the packing pocket. A

'lhepart, 3, of the pocket comprises a stout ring having its inneredgciinishdiii: at 6 to form a seat for the bull member 1. it 'isprovided with a number of bolt holes, for the accomn'iodation of bolts7, which pass therethrough and into a flange 8 formed on the part 2. Itwill be seen that all the wear is upon i'netallic surfaces, the bull isheld between the seat (3 of the part 3 and a seat. 5) formed in thebottom of the part 2; and also that the wear may be readily taken up bytightening the bolts 7. The face of the part 3, which is contiguous tothe part 2, is provided with an annular groove, 10, of an outsidedizimcter equal to that of the packing pocket 4. \Vithin the groove .10,is'scatcd u ring 11, which bridges the gap between 'the socket memberand the follower, and cxtcnd.--; into the said packing pocket. "lhus, itwill be seen, by reference to the drmvings that the packing is confinedbetween the outer walls of the pocket 4:, the flange the ring 11, and asmall portion of the part 2-; of the socket member. A. plurality ofscrews 12 are tapped through the part 3 and impinge against the upperface of the ring 11. By tightening the screws 12 the ring 11 is pressedinwardly upon the packing, tightly 'wedgin the same in the pocket. Thelower, inner e go of the ring 11 is beveled as indicated at 18, toprevent it from impinging against the bull meml'ior 1, when pressed inanenlarged wardly. It should be noticed that there is no possible way torthe packing or any pormatter how great the pressure Which is appliedthrough the ring, 11, and screws 12. It is also to be noted that allstrain tending to separate the joint is upon the metallic parts only,and. that none of it is upon the soft packing or upon non-metallicgaskets, as is frequently the case with joints of this character now inuse. This particular flexible joint may be modified without de partingfrom my invention, and 1 do not confine the invention to the specificconnec tion herein shown and described.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a flexible fluid joint for pipes, a ball member in combinationwith a two part socket member, said socket member being provided with apacking pocket extending inwardly to a plane beyond the center of thesocket, a metallic closure arranged in the outer-end of the pocket andclosing the joint between the parts of the socket member, and

l l l l means for forcing said metallic closure into said pocket,substantially as described.

2. In a flexible l'luid joint for pipes, a. ball member in con'ibinationwith a two part socket member, packing pocket in one part of said socketmember, an annular recess in the other part thereof, a metallic closurearranged in said annular recess and extending into said pocket to closethe joint or opening between the parts of said socket member, and meansfor forcing said metallic closure into said pocket, substantially asdescribed.

In a flexible pipe, a ball member, in combination with a socket member,compris ing relatively adjustable parts; said socket parts togethercontaining a packing recess and an adjustable metallic packing-iillower, 1

arranged in said recess, and closing the joint between the parts of thesocket member, substantially as described.

In testimony whereof, .l. have hereunto set my hand, this 29th day ofMay, 1906, in the presence of two subscribing witnesses.
